While Houston officials didn't establish a mandatory evacuation for the entire metropolis, some residents fled to neighboring cities like Dallas, Austin, and San Antonio before the rains, tornadoes, and floods came to the city.

Now, many of those residents are wondering if it's safe for them to head back into the city with reports of major roadways still being closed due to high water and damaged roads.
